WHAT IS SUPREME ULTRA HD?
SUPREME ULTRA HD is Royal’s answer to the requirements of a CJ-4 oil, designed primarily for post-2007 diesel engines. It was during this time that additive restrictions were placed on oil manufacturers, and engines saw dramatic changes with the incorporation of EGR and particulate filtration systems. Through all of the changes, SUPREME ULTRA HD emerged as the premier oil for the time, still boasting an industry high 14 TBN and exceptional extended drain capabilities.
HIGH TBN
87 years of world-class manufacturing experience has enabled Royal Oil Co. to develop the most robust Total Base Number in the industry, miles ahead of other CJ-4 oils on the market.
DISPERSES SOOT
SUPREME ULTRA HD is formulated with powerful dispersant chemistry to keep soot dispersed into finer particles, which results in reduced oil thickening and improved protection against abrasive wear.
OXIDATION PROTECTION
SUPREME ULTRA HD provides increased soot control. Royal Oil Co.’s SUPREME ULTRA HD contains top of the line dispersants to control soot thickening, sludge, and varnish as well as keep other deposit precursors suspended in the oil so that they can be filtered out.
ADVANCED DETERGENTS
SUPREME ULTRA HD offers the most advanced detergent package among CJ-4 oils in the industry today. SUPREME ULTRA HD’S ability to eliminate the build-up of existing varnish, gum or sludge at changeover is critical to extending engine life.
